Pdf Text Extraction And Indexing

via “pdf processing with table-of-contents extraction and page-range tracking”

📑 PageIndex: Document Index for Vectorless, Reasoning-based RAG

Unique: Automatically extracts and reconstructs document hierarchy from PDF table-of-contents and structure metadata, enabling accurate page-range tracking without manual annotation. Treats TOC extraction as a first-class operation rather than a preprocessing step.

vs others: More accurate than generic PDF chunking because it respects natural document boundaries from TOC rather than splitting at arbitrary token counts, and maintains page references for source attribution that vector RAG systems typically lose.
